Glances can trigger actions on events.

By action, we mean all shell command line. For example, if you want to execute the script if the last 5 minutes load are critical then add the _action line to the Glances configuration file:

critical_action=python /path/to/

All the stats are available in the command line through the use of the {{mustache}} syntax. Another example would be to create a log file containing used vs total disk space if a space trigger warning is reached:

warning_action=echo {{mnt_point}} {{used}}/{{size}} > /tmp/fs.alert


You can use all the stats for the current plugin. See for the stats list.

It is also possible to repeat action until the end of the alert. Keep in mind that the command line is executed every refresh time so use with caution:
